C++ has lots of data structures built in. One of the simplest to use is
called a vector. Here's a little sample
#include <vector>
#include <string>
struct Command
{
std::string name;
std::string command;
int time;
};
// here's your vector of commands
std::vector<Command> command_vector;
// here's how to add a command to the command vector
Command a_command;
command_vector.push_back(a_command);
// here's how to loop though all the commands
for (int i = 0; i < command_vector.size(); ++i)
print_command(command_vector[i]);
etc. etc.
Any decent C++ book will talk about the vector class and a whole lot more.
Perhaps you need to invest in one?
